camiller - you sure that that motor has the sand to even crush grain? I wouldn't imagine that a wiper motor has that much torque.
Working Torque - 3.98 foot pounds (5.4 N m) - seems to be cutting it pretty close. You probably won't be able to start the mill up with grain in it, at a minimum.
I didn't notice (or don't remember) a plastic bushing on my victoria - will have to check.
Never used a gear motor before, any help with me picking a proper setup? Based on a quick google they seem ridiculously $$
I put a bar type torque wrench on my mill to try to estimate the amount of torque required to turn it and I think I will be OK. I think the Static Torque of 13.27 foot pounds will be enough to get it going from a stop, and once it is going the ~4 should keep it going. There is another wiper motor corona thread around here (found it: https://www.homebrewtalk.com/f51/windshield-wiper-motor-powered-grain-mill-164285/ ) but it did use a significantly beefier wiper motor from a semi truck. At any rate, I'm going to give it a try, $16 isn't too much for an experiment.
If you are looking for a better gear motor keep an eye on the surplus sites like http://www.surpluscenter.com/sort.asp?catname=electric&keyword=GIAR
